UNITED sratrns PATENT O v ELI BROTHERS, or LYNN, MASSACHUSETTS, assreuon T0 UNITED s'HoE MACHINE-RY COMPANY, or PATERSON, new JERSEY, A CORPORATION on: NEW JERSEY.

To all whom it may concern:

Be it'k nown that I, ELI BRo'rHERs,]a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented .certain new .and useful Improvements in Machines for Operating on Shoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artTto which it appertains to make and use the same.

The present invention relates to machines for operating upon shoes in which the point of operation of the operating megihanism is transferred around the shoe. In the opera tion of machines of this class the shoe is usually supported in the hand of the operator and is manipulated by him to properly present the different portions thereof to the mechanism for operating thereon. The movements which are imparted to the shoe by the operator during the operation of the machine thereon consist of lateral turning movements to bring the margin of the sole adjacent the pointof operation into a position substantially parallel with the line of feed, and lateral and longitudinal tipping or tilting movements to bring the portion of the shoe in proximity to the operating mechanism into the desired plane. Machines have been devised in which the shoe is supported upon a movable jack and relative movements are automatically imparted to the operating mechanism and the jack to bring the shoe into proper relation to the operating mechanism. These machines are complicated in construction and expensive to manufacture.

The primary object of the present invention is to produce an improvedand simplified machine for operating on shoes by which the shoe is supported and automatically manipulated to properly present the various portions thereof to the operating mechanism as the point of operating of said mechanism is transferred around theshoe.

In carrying out the above object, one

feature of the invention contemplates the provision in a machine of the class referred to of a shoe supporting jack, a track secured to said jack, and guides engaging said track and coiiperating therewith to impart tipping and lateral turning movements ttfl the jack.

Other features of the invention consist in certain constructions, arrangements and Specification of Letters Patent.

combinations of parts, the advantages of which will be obvious to one skilled in the art from the following'description.

In the drawings illustrating the invention n the best form at present known to the 1nventor;Figure 1 is a side elevation ofa portion of a shoe sewing machine embody ng the invention illustrating a shoe in posit on on'the' shoe supporting jack; Fig.

2 is v a detail front elevation of the shoe supporting 130k, the track secured to the ack and-the table supporting the jack; Fig. 3 1s a plan view of aportion of the'mec anlsm shown in Fig. 2; Fig. 4 is a front elevation of the guides for engaging the track and the mechanism supporting the guides, showing certain parts thereof in position to per] it the insertion of the track; Fig. 5 i's-a sectional view taken on the line 55 of Fig, 4, showing the parts 5 in operative position.

The present invention as illustrated in the drawings has been embodied in a Goodyear welt and turn shoe sewing machine of the type disclosed in-the patent to French &

Meyer, 413,704, Only so much of the sewing mechanism as is necessary for a clear understanding of the invention has been shown in the drawing. The curved hook needle is indicated at 1, the feed point at 2 and the-channel guide at 3, all of these parts being constructed, arranged and operated as shown and described in the French & Meyer patent. As is well known to those skilled in the art, in sewing machines of this type, the, feed point is brought forward at intervals to engage the shoe and is moved laterally together with the channel guide to impart feeding movements to the shoe, thereby transferring the point of 5f operation of the stitch forming mechanism about the shoe.

The lasted shoe is' supported by a jack adapted to hold ordinary wooden lasts, upon I which welt and turn shoes are lasted. This jack is indicated as a whole at 4 and is provided with the usuallast pin 5 carried by the block 6 pivoted at 7upon a segmental block 8'and held in position with relation to said block by a pawl 9 which is arranged to engage teeth 10 formed on said block. The segmental block 8 is arranged for ad-' justment on the supporting plate 11 of the jack frame-to accommodate lasts of different sizes by providing the plate 11 with a'slot no 11 and securing the block 8 to the plate by a clamping s cr'ew 8 passing through the slot and screwedinto the block. A toe sup port 12 is carried .by a supporting bolt 13 mounted in'an arm 14 of thej a'ck frame. In order to provide for the transverse adjustment of the support, said support is formed with a transverse groove 15 shaped to receivethe head of the supporting bolt 13, and

theisup'port is clamped'in adjusted position on said bolt by a nut 16. The bolt 13 is received in perforations in spaced'portions of athe arm lt, andthe toe support is adjusted for lasts of different, sizes by means ofthe 11111517 threaded on said bolt and interposedbetween the :spaced portions of the arm.

The jack is mounted upon a standard 18 and 'is supported to maintain the shoe inposition to be engaged by the feed point and-the channel guide by means of a table 19 mountedona rod 20 arranged to slide vertically in a bracket .21 and pressed upwardly by a lever 22 operated by a counterbalance weight 23. By. this means the shoe is also maintained in engagement with the feed point and channel guide duringthe feed m'ovementsth-ereof. In order to permit the jack to tip laterally and. longitudinally to,

sling a portion of the shoe at the point of peration of the sewing mechanism into the proper plane, the jack is connected to the standard 18 by any suitable form of uni versal joint indicated at 24. The standard 18 isprovided with antifriction rolls 25 so that the standard moves freely over the surface of the'table during the movements imparted-to the jack in the sewing operation.

The'mechanis'm for actuating the. jack to bring the shoe into proper relation tothe sewing mechanism as the point of operation track therefore forms a pattern curved to correspond approximately to, the curvature ofthe marginal portion of a shoe sol. The inner and outer faces of the track are formed so thatthe elements of these surfaces vary in angular position in different portions of the track. In the construction illustrated the angular position of the elements of the lateral surfaces at the toe portion is varied from that at other portions thereof, as is clearly shown in Fig. 1. A series of guides are arranged to engage this track and cooperate therewith to move the jack to prop erly present the shoe to thestitch forming mechanism as the shoe is fed. In the pres ent embodiment of the invention these guides consist of a plurality of guide rolls engaging the upper and lower edges and the inner and outer faces of the track. A

pair of-these guide rolls engaging the upper edge of the track are indicated at 27. These rolls are mounted on an arm 28 of a member 29 carried by guide rods 30-and :51 arranged to slide in sleeves 32 and 33 formed on a hanger 34 piy otally supported by a shaft 35 carried by spaced arms 36 and 37 supported by slides 38 and 39. Coiled springs 40 and 41 surrounding the guide rods'30 and3'1 are interposed between the sleeves 32 and 33 and the member 29 to resiliently support the said member. A second pairfof I guide rolls 42 are carried by the member 29 and are arranged to engage the-lower edge of the track in opposed relation to the rolls 27. In order to prevent binding ofthe track 35 between'the guides due to the curvature of the track, the rolls. 42.are mounted upon pins 43 arranged to slide in guides 44 in the member 29 and are resiliently held against the lower edge of the track by coil springs 45. A third pair of guide rolls 46 arranged to engage the outer face of the track are mounted in the member 29 upon pins 47 arranged to move in guides 48 in the member 29 and are resiliently held in engagement withthe track by coil springs 49. Guide rolls 50 are arranged to engage .the inner face of the track in opposedirelation to the rolls 46, In order to permit the removal of the track from between the guide rolls and the substitution of another of different shape v or' size, the rolls 50 are mounted upon a swing, frame '5larranged to swing on a shaft 52 carriedby the, member 29 so that the frame 51 maybe swung downwardly 1% into the position shdwn in Fig. 4. When the track is inserted in position between the guide rolls, the swing frame 51 is swung upwardly to bring the rolls 50 into engage- 'ment with the inner face of the track and is then'locked in position by a screw pin 52- which is passed through a perforation in the swing frame 51 and through a registering perforation in an "arm 53 formed on the member 29. In order to provide for angular adjust- 4 ment of the guides to vary the angular position of the jack, the hanger 34 is provided with a segment 54 in which are formed a series of perforations tions. 17m

A projection 56 129' 'on the arm 37 extends downwardly in front I.he slide 38 which cooperates .with the slide 39 in supporting the guide mechanism 1s constructed, arranged and operated in the same ,manner as the back gage of the 5 sewing. machine of the French & Meyer patent referred to above. The guides are therefore free to move transversely of the verticalplane of the line of feed during the feed movement of the shoe thereby permitting the; shoe to assume the desired position with relation to the sewing mechanism, .51 3 are locked in position during the opera {ti'on of the stitch forming; mechanism to firmly support the jack and shoe against the act ion of said mechanism.

vIll "the operation of sewing a shoe, the lasted shoe is first placed in position on the jack withthe channel guide of the sewing mechanism engaging the channel of the shoe in the well known manner, the shoe being held :in engagement with the channel guide by; the jack supporting table 19. When the 'ewing mechanism is in operation, feed movements are imparted at intervals to the shoeb the lateral movement of the feed point 2 thereby moving the jack upon which the shoe is supported at intervals in the d1- frection of the line of feed, and during these -movements of the jack, the track 26 moves flofforwardly through the guide rolls of the guide mechanism. By the engagement of the guides with the curved lateral faces "of the track, lateral turning movements are ,imparted to the jack to place the margmof a position. substantially parallel with the "line of feed. The engagement of the guides with the curved edges of the'track during themovements thereof causes tipping movements to be imparted to the jack angular-1y .with'respect to the line offeed. By reason i ,of the formation 'of the lateral faces of the track so that the elements thereof vary in "angular position, tipping movements are imparted thereto about an axis substantially coincident with the .line of feed. Inasmuch as these movements take place only during the feed movement of the shoe when the feed" point is in engagement with the sole, the lateral turning and longitudinal and lateral tipping movements which are impar'ted to the jack take place about the point .of operation of the stitch forming mecha-- nism.

' Although the invention has been shown and described as embodied in a shoe sewing machine, certain features thereof may be embodied in other machines in which the point of operation of the operating mechanism is transferred about the shoe, such as pegging and nailing machines, lasting machines, sole edge trimming and fin shing machines, etc.
